There is an old hp300 series machine here that I can have if I want
it, but it is missing its keyboard and mouse.  It is a desk-side unit
with a 1-slot VME cage in the top, a CPU box, a disk box, and a tape
box.  It has RGB video outputs and a cable that produces a nice image
when connected to a Sun color monitor.  It even tries to boot, but
asks for some keyboard interaction, so I need a keyboard.

Anyone know how to determine which model it is?  (and CPU speed?)
Where might I find a keyboard/mouse for this thing?
